Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The present invention will be described in detail below with reference to specific examples.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for implementing an interface function according to an embodiment of the present invention, where the method is applied to an uplink device connected to a communication device. Among these, the communication device can be understood as: the hardware and the software are simple communication equipment and do not have functional modules corresponding to the interface functions to be realized; the uplink device can be understood as: the communication equipment is provided with a functional module corresponding to the interface function to be realized.
Generally, a CPU (Central Processing Unit) and a memory of a communication device, both hardware and software of which are relatively simple, are relatively weak, and may cause a device crash when Processing relatively complex data calculation, while a CPU and a memory of an uplink device are relatively strong, and may process relatively complex data calculation, and a complex interface function is more easily implemented by using the uplink device.
In one embodiment of the present invention, the communication device may be an AP, a sensor, an internet of things node, or the like; the uplink device may be a switching device, an Access Controller (AC), or a convergence device.
Specifically, the method for implementing the interface function includes:
s101: when the communication equipment does not have a functional module corresponding to the interface function to be realized, creating a virtual network card corresponding to the communication equipment according to the interface information of the communication interface of the communication equipment, and setting a virtual communication interface corresponding to the communication interface on the virtual network card;
after the connection between the uplink device and the communication device is established, if the communication device needs to implement an interface function (which may be understood as an interface function to be implemented), but the communication device does not have a functional module corresponding to the interface function to be implemented, and the uplink device has a functional module corresponding to the interface function to be implemented, the uplink device may acquire interface information of a communication interface of the communication device from the communication device, for example: the number of communication interfaces, the load state of the communication interfaces, and the like; according to the acquired interface information, the uplink device can create a virtual network card corresponding to the communication device, and set a virtual communication interface corresponding to the communication interface of the communication device on the virtual network card. Here, the interface information of the virtual communication interface of the virtual network card matches the interface information of the communication interface of the communication device.
In an embodiment of the present invention, each functional module may implement one interface function, and in order to implement multiple interface functions, at least one functional module is configured on the uplink device; in addition, the uplink device may be connected to at least one communication device, so that when the interface function of the communication device is implemented, that is, when the interface function of the communication interface of the communication device is implemented, the network construction cost may be reduced. For example, n communication devices are connected with the uplink device, and n virtual network cards can be created on the uplink device, so that the number of the uplink devices configured for realizing the interface function of the communication device is reduced, and the network construction cost is reduced; in addition, from the perspective of the uplink device, creating a virtual network card on the uplink device can be understood that the communication device is inserted into an expansion card of the uplink device, so that the interface function on the communication device is very easily implemented when the uplink device has a function module corresponding to the interface function required by the communication device.
S102: sending an interface state setting request aiming at the virtual communication interface to a forwarding module of the communication equipment through the forwarding module of the uplink equipment;
in this case, the communication device may obtain the interface state setting request, and further set the interface state of the communication interface according to the interface state setting request.
Generally, the interface state is set to realize the interface function, which is only specific to the local device, that is, the uplink device can only set the interface state of the communication interface or the virtual communication interface of the local device, realize the interface function of the communication interface or the virtual communication interface of the local device, and cannot realize the interface function of the communication interface of the communication device connected to the local device. In this case, in order to implement the interface function of the communication interface of the communication device through the uplink device, a forwarding module may be disposed on both the uplink device and the communication device, and the work conversion between the real communication interface of the communication device and the virtual communication interface of the uplink device is completed through the communication between the forwarding modules, that is, the difference between the real communication interface of the communication device and the virtual communication interface of the uplink device is shielded, so that the uplink device considers that the virtual communication interface is the real communication interface.
In an embodiment of the present invention, referring to fig. 2, the structures of the uplink device and the communication device provided with the forwarding module may be that the virtual network card 200 corresponds to the communication device, and the virtual communication interface 500 corresponds to the communication interface 600. In this case, the interface state setting request may be understood as that the function module 100 creates and transmits to the virtual network card 200, and then the virtual network card 200 transmits to the forwarding module 300 of the uplink device. Based on the above, S102 may be:
the function module 100 creates an interface state setting request and sends the interface state setting request to the virtual network card 200;
the virtual network card 200 then sends the interface state setting request to the forwarding module 300 of the uplink device;
the forwarding module 300 then sends the interface state setting request to the forwarding module 400 of the communication device.
Thus, the communication device can obtain the interface state setting request through the forwarding module 400, and further set the interface state of the communication interface 600 according to the interface state setting request. For example, the interface status setting request is a BLOCK status setting request, and the communication device may set the communication interface to a BLOCK status. After the communication device sets the interface state of the communication interface 600, the communication interface 600 may filter the received message, that is, discard the message that does not match the interface state, and keep the message that matches the interface state.
It should be noted that the communication device may include at least one communication interface, and at this time, the virtual network card established on the uplink device for the communication device is provided with the corresponding at least one virtual communication interface. In addition, the interface function may be for a certain communication interface, in this case, in order to accurately set the interface state of the communication interface and implement the interface function of the communication interface, the forwarding module may receive an interface state setting request of which virtual communication interface from the virtual network card, and the communication device corresponding to the virtual network card may set only the interface state of the communication interface corresponding to the virtual communication interface.
S103: receiving, by a forwarding module of the uplink device, a protocol packet that is sent by the communication device through the forwarding module of the communication device and matches the interface state;
after a communication interface of the communication equipment obtains a protocol message matched with the interface state, the communication interface sends the protocol message to a forwarding module of the communication equipment, and the forwarding module of the communication equipment sends the protocol message to a forwarding module of the uplink equipment. Referring to fig. 2, the forwarding module 300 may send the protocol message to the virtual network card 200, and then the virtual network card 200 sends the protocol message to the function module 100; at this time, the functional module 100 considers that the protocol message is received by the virtual communication interface 500 of the virtual network card 200, and the virtual communication interface 500 of the virtual network card 200 needs to implement an interface function.
S104: and processing the protocol message through a functional module of the uplink equipment.
In this case, the interface function of the communication interface of the communication device is completed by the upper link device, for example, the interface state setting request is issued by the upper link device, the protocol packet is processed by the upper link device, and the like, so that the auxiliary communication device realizes the complex interface function of the communication interface of the communication device.
After receiving the protocol message, the function module of the uplink device processes the protocol message, determines the next interface state of the virtual communication on the virtual network card according to the information in the protocol message, and sends the setting request of the next interface state to the forwarding module of the communication device through the forwarding module of the uplink device so as to set the next interface state of the communication interface of the communication device.
The following describes in detail the implementation process of the interface function, taking the switch device as an uplink device, the panel AP as a communication device, and the switch device assists the panel AP to implement an STP (Spanning Tree Protocol) function of the LAN interface, specifically:
A. after the switching equipment establishes connection with the panel AP, the switching equipment acquires interface information of an LAN port of the panel AP, creates a virtual network card corresponding to the panel AP, and sets a virtual LAN port corresponding to the LAN port on the virtual network card;
here, the switching device may always store the virtual network card and the related virtual LAN port created for the panel AP, so that the virtual network card and the related virtual LAN port do not need to be created again when being reconnected after being disconnected from the panel AP, and can be directly used; of course, the created virtual network card and the relevant virtual LAN port may be deleted after the connection with the panel AP is disconnected, and the virtual network card and the relevant virtual LAN port may be created again by using the step a when the connection with the panel AP is made again.
B. The switching equipment starts an STP function module, the STP function module sends an interface state setting request for setting the interface state of a virtual LAN port to be a BLOCK state to a virtual network card, and the virtual network card sends the interface state setting request to a forwarding module of the switching equipment;
C. the forwarding module of the switching equipment sends the interface state setting request to the forwarding module of the panel AP;
D. and the forwarding module of the panel AP sets the LAN port of the panel AP to be in a BLOCK state according to the interface state setting request. At this time, the LAN port of the panel AP discards the received messages except for the BPDU (Bridge Protocol Data Unit) Protocol message, and sends the received BPDU Protocol message to the forwarding module of the panel AP, where the forwarding module of the panel AP forwards the BPDU Protocol message to the forwarding module of the switching device instead of processing the BPDU Protocol message.
E. After receiving the BPDU protocol message, a FORWARDING module of the switching device sends the BPDU protocol message to a virtual network card, and then the virtual network card sends the BPDU protocol message to an STP functional module, and the STP functional module considers that the BPDU protocol message is received by the virtual network card, and performs STP calculation according to the BPDU protocol message to obtain a next interface state (e.g., rwforward state) of the virtual LAN interface;
E. the STP function module sends an interface state setting request for setting the interface state of the virtual LAN port to a FORWARDING state to the virtual network card, the virtual network card sends the interface state setting request to a FORWARDING module of the switching equipment, the FORWARDING module of the switching equipment forwards the interface state setting request to a FORWARDING module of the panel AP, the FORWARDING module of the panel AP sets the LAN port of the panel AP to the FORWARDING state, the subsequent processing process is similar to the processing process after the panel AP sets the LAN port to a BLOCK state, and the FORWARDING module of the panel AP forwards a protocol message matched with the FORWARDING state to the FORWARDING module of the switching equipment and finally the protocol message is processed by the STP function module.
As can be seen from the above example, by setting the forwarding module and creating the virtual network card on the switching device, the LAN port on the remote panel AP can be virtualized on the switching device, so that the complex interface function of the LAN port can be realized by using the existing functional module with the complex interface function on the switching device and the auxiliary panel AP, thereby improving the user experience.
In an embodiment of the present invention, by applying the implementation method of the interface function, an authentication function of the panel AP LAN port may also be implemented, for example, an 802.1X authentication function of the panel AP LAN port needs to be implemented, which is similar to the above-mentioned process of implementing the STP function of the panel AP LAN port, and is different from the following steps:
01. the function module is an authentication function module, and the interface function is an 802.1X authentication function;
02. the message matched with the interface state is an EAPOL (Extensible Authentication protocol overlay Lan, based on the local area network) message;
03. the Authentication function module needs to communicate with an AAA (Authentication Authorization Accounting) server according to the EAPOL message to determine the state of the relevant interface.
It should be noted that the interface function may also be other complex interface functions, which are not listed here.
The embodiment of the invention provides a method for realizing an interface function, wherein a virtual network card corresponding to a communication device is arranged on an upper connection device of the communication device, a virtual communication interface corresponding to the communication interface is arranged on the virtual network card, when the interface function of the communication interface of the communication device is realized, the communication between the upper connection device and the communication device is realized through a forwarding module, the work conversion between the communication device and a virtual network card on the upper connection device is completed, the upper connection device considers that the virtual network card is the communication device, the communication device with simpler hardware and software realizes the complex interface function, and the user experience is improved.
It should be noted that, the step 101 may be implemented by a creating module separately disposed on the uplink device (that is, creating a virtual network card by the creating module and disposing a virtual communication interface on the virtual network card), and the communication interface of the communication device is assisted to implement a complex interface function through interaction between the function module of the uplink device and the creating module, interaction between the creating module and the forwarding module of the uplink device, and interaction between the forwarding module of the uplink device and the forwarding module of the communication device.
Of course, the step 101 may also be implemented by the forwarding module on the uplink device (i.e., creating a virtual network card by the forwarding module and setting a virtual communication interface on the virtual network card), and the communication interface of the communication device is assisted to implement a complex interface function through interaction between the function module of the uplink device and the forwarding module, and interaction between the forwarding module and the forwarding module of the communication device.
For example, in another embodiment of the present invention, the structures of the uplink device and the communication device provided with the forwarding module may refer to fig. 3, where the virtual network card 200 corresponds to the communication device, and the virtual communication interface 500 corresponds to the communication interface 600. In this case, the interface state setting request is created for the function module 100 and transmitted to the forwarding module 300 of the connected device. Based on the above, S102 may be:
the function module 100 creates an interface state setting request and sends the interface state setting request to the forwarding module 300 of the uplink device;
the forwarding module 300 then sends the interface state setting request to the forwarding module 400 of the communication device.
Thus, the communication device can obtain the interface state setting request through the forwarding module 400, and further set the interface state of the communication interface 600 according to the interface state setting request.
Here, before the forwarding module 300 sends the interface state setting request to the forwarding module 400, the forwarding module 300 may determine the virtual network card 200 corresponding to the interface state setting request according to the interface information of the virtual network card 200 created by the forwarding module 300 (this situation is suitable for the case where the forwarding module 300 creates a plurality of virtual network cards), further determine the communication device corresponding to the interface state setting request, and then send the interface state setting request to the forwarding module 400 of the determined communication device.
It should be noted that the communication device may include at least one communication interface, and at this time, the virtual network card established on the uplink device for the communication device is provided with the corresponding at least one virtual communication interface. In addition, the interface function may be for a certain communication interface, and in this case, in order to accurately set the interface state of the communication interface and implement the interface function of the communication interface, the forwarding module may determine, according to the interface information of the virtual network card created by the forwarding module, the virtual network card corresponding to the interface state setting request and the virtual communication interface of the virtual network card corresponding to the interface state setting request, further determine the communication device corresponding to the interface state setting request and the communication interface of the communication device corresponding to the interface state setting request, and then send the interface state setting request to the forwarding module of the determined communication device. In this way, the forwarding module can set only the determined interface state of the communication interface.
In addition, after the communication interface of the communication device obtains the protocol message matched with the interface state, the communication interface sends the protocol message to the forwarding module of the communication device, and the forwarding module of the communication device sends the protocol message to the forwarding module of the uplink device. Based on fig. 3, the forwarding module 300 may directly send the protocol packet to the functional module 100; at this time, the functional module 100 considers that the protocol packet is received by the virtual communication interface of the virtual network card 200 created by the forwarding module 300, and the virtual communication interface of the virtual network card 200 needs to implement an interface function.
Referring to fig. 4, fig. 4 is a flowchart illustrating another implementation method of an interface function according to an embodiment of the present invention, where the method is applied to a communication device. Among these, the communication device can be understood as: hardware and software are simple communication devices, and do not have functional modules corresponding to the interface functions to be realized.
S401: when the communication equipment does not have a functional module corresponding to the interface function to be realized, sending interface information of a communication interface of the communication equipment to the uplink equipment of the communication equipment;
therefore, the uplink device can create a virtual network card corresponding to the communication device according to the interface information of the communication interface, and set a virtual communication interface corresponding to the communication interface on the virtual network card.
Here, the uplink device may be understood as: the communication equipment is provided with a functional module corresponding to the interface function to be realized.
In one embodiment of the present invention, the communication device may be an AP, a sensor, an internet of things node, or the like; the uplink device can be a switching device, an AC or a convergence device, etc.
S402: receiving, by a forwarding module of the communication device, an interface state setting request for the virtual communication interface sent by the uplink device through the forwarding module of the uplink device
S403: setting the interface state of the communication interface according to the interface state setting request through a forwarding module of the communication equipment;
after the communication device sets the interface state of the communication interface, the communication interface can filter the received message, that is, discard the message that does not match the interface state, and keep the message that matches the interface state.
S404: and sending the protocol message which is received by the communication interface and matched with the interface state to a forwarding module of the uplink equipment through the forwarding module of the communication equipment.
